SO many devices and metrics. But can they really help you recovery and perform better?


What about HRV?

Heart rate variability (HRV) is getting a lot of attention these days, as are other metrics on devices that measure 'recovery' and 'stress scores'. I wanted to get clear on the differences between these data, how athletes can use them, how accurate they are and what the most accurate devices and apps on the market are.


Don't worry, if this is all new, I've got you! This is the exact purpose of the podcast, to demystify this topic.


HRV is related to the heart and measuring physiological stress. Essentially it's the variability between the times between each heartbeat. Since our heart does not beat at a consistent frequency, the time between heart beats can be more constant or more variable and that's what HRV is measuring.


Rather than get into how the autonomic nervous system relates to this, I will let Dr. Marco Altini explain! We made sure to keep this simplified so that it translates to all listeners. There's so much more to learn and understand about why HRV is relevant and how understanding yours can help you manage your training load and recovery.


To make sure I got all the facts, I reached out to Dr. Marco Altini.




Dr. Altini, who has been working in the HRV space for over a decade is on the scientific advisory board for OURA ring, has worked with Strava and has his own app HRV4Training.com which also measures HRV.


I've read several of his studies and am impressed with his background for it's well roundedness that suits this passion perfectly.


Dr. Altini has his PhD in applied machine learning, a M.Sc. in computer science engineering and is currently enrolled in a M.Sc. in human movement sciences and high-performance

coaching. He has published more than 50 papers and patents related to physiology, health, technology and human performance. Currently, he is leading product development & research for HRV4Training, he’s also a passionate runner and today we talk about his first experience at a 100km running race and what he’s doing for his comeback for version 2.0. It’s always great when guests are putting the science into motion personally and professionally as many of my guests do.


We did our best to make this podcast super accessible by defining terms and physiology upfront. Grab a pen and paper though as there's a lot to remember!


Here's what you'll learn today:
